Eccentric Bushing
Identify parts for Metso cone crushers, check models and drawing, confirm materials and processes, and submit an inquiry.
Equipment and Applicable Models
Identify the installed machine model and key dimensions, then check the drawing revision and physical interfaces.
Models and Key Dimensions
Metso HP series (HP100-HP800), GP series (GP100-GP550), and MP series (MP800-MP1000)
Materials and Processes
Select the material grade and heat treatment for the operating conditions, processed material and equipment specifications. The options below are commonly used; confirm the final grade against the drawing and technical agreement.
C95400 aluminum bronze (ASTM B148)
Candidate aluminum bronze; verify casting and heat treatment condition, composition and mechanical properties against the eccentric bushing drawing and material standard.
Aluminum bronze C95500 (ASTM B148)
Candidate nickel-aluminum bronze; confirm suitability for heavy loading and mechanical properties for the specified material condition and part drawing.
C93200 leaded tin bronze (SAE 660)
Candidate leaded bearing copper alloy; select for the load, speed and lubrication conditions. The material cannot replace the lubrication required by the equipment.
Wear Characteristics and Replacement
Common wear modes and maintenance advice. The actual replacement interval depends on duty, material and operating data.
Common wear modes
- Eccentric mainshaft loading causes uneven bushing bore wear, concentrated in the direction of eccentric loading
- Inadequate lubrication causes bushing scuffing and seizure; severe cases can weld the bushing to the mainshaft
- Foreign particles in the lubricant cause axial grooves in the bushing surface
- Fretting between the bushing outside diameter and housing bore loosens the fit
Replacement criteria
Check bushing wear and fitting clearance against the maintenance manual. Stop and inspect if the stroke becomes abnormal, copper debris keeps increasing, or surfaces show seizure or scoring. Base replacement on actual damage and model-specific limits. Control interference between the outside diameter and housing bore to the drawing.
Material and Process Control
Materials, heat treatment, composite processes and inspection follow the specific drawing, duty and technical review.
Material Grade / Substrate
The material grade and applicable standard must follow the drawing or confirmed technical specification for the machine model. Candidate materials on this page are not an OEM grade designation.
Heat Treatment Condition
Select the heat treatment condition for the specific copper alloy grade and part drawing; verify final hardness and microstructure against the technical agreement.
Composite / Hardfacing Requirements
Bronze bushings are not suitable for weld overlay repair. Replace the worn bushing as a complete part; surface repair is not recommended.
Dimensions and Inspection
Manufacture to drawings produced from part measurements or supplied by the customer. Critical mating surface tolerances follow OEM requirements. Specify nondestructive testing methods suitable for the material and part geometry. Agree the inspection scope and acceptance criteria in the technical specification.
Parts with the same name may not be interchangeable across models, drawing revisions, interfaces and materials. Confirm the full model, serial number and drawings before manufacture.
